I have tried multiple version setups with no success attempting to create a Custom Cluster “Use existing nodes and create a cluster using RKE” My use case is a single node for a home lab setup. Please help.

  • Install similar to youtube “Docker, Rancher, Kubernetes… Minecraft? (Rancher Setup and Install Tutorial)”
  • installed ubuntu server 20.04.4 LTS with no updates or upgrades (except QEME guest agent for IP recognition via proxmox)
  • made several attempts at various versions as outlined here Support matrix | SUSE
    curl https://releases.rancher.com/install-docker/20.10.sh | sh
    sudo usermod -aG docker $USER
  • logged out then back in to enable
    docker run -d --restart=unless-stopped -p 9090:80 -p 9091:443 --privileged -v /opt/rancher:/var/lib/rancher --name=rancher_server rancher/rancher:latest

The steps you’ve listed are for installing the Rancher server. Once you’ve done that you need to go through the UI to create a new cluster. That will give you a docker command to run on each of the nodes you want to run the cluster on.

What step is failing and what error are you getting?

He got error messages in the title.
